Abstract: Provided are a vehicle card key and a method of manufacturing the same. The vehicle card key is used to lock/unlock a vehicle door or start an engine in wireless communication with a vehicle. The vehicle card key includes a lower cover, a circuit board stacked on and coupled to a top of the lower cover, and an upper cover coupled to the lower cover as one body to cover an upper side of the circuit board. The lower cover and the upper cover are formed of a thermo-hardening resin.

Abstract: An apparatus and a method for automatically performing self-diagnosis are provided. In the method, when an external storage unit is connected, files stored in the external storage unit are searched for. When a diagnosis file for self diagnosis is stored in the external storage unit, information of at least one item required by the diagnosis file is collected. The collected information is stored as an output file in the external storage unit.

Abstract: A system to manage socket connections and method of checking connections include: at least one application program module adapted to create a socket necessary for communication of a server or a client and calling an Application Program Interface (API) defined to check a socket connection to manage the created socket; a common library module containing a program coded to perform an operation set in an API when the API is called from the application program module; and a socket check execution module created by executing the coded program in the common library module to periodically check the socket connection of the created socket.

Abstract: A system and method for a Trivial File Transfer Protocol (TFTP) includes a broadcasting function in which a new option is added to the TFTP to allow several clients to connect with one server to simultaneously download files.
